관리미제사건의 효율적 관리를 위한 제도 정비 방안 : 실무 운영의 한계와 개선 과제

This thesis analyzes the practical limitations of the Registered Unsolved Case Management System, which was introduced in 2021, and proposes improvement measures.　 The current system registers and manages cases where the suspect cannot be identified and thus cannot be closed. While it aims to balance the realization of criminal justice with investigative efficiency, the system faces significant challenges. Despite exponential growth from approximately 3.67 million cases in 2020 to 4.63 million cases as of August 2025, the reinvestigation rate remains as low as 1.8%, indicating that the system fails to fulfill its original purpose.　 The main problems with the current system are as follows: First, ambiguity and arbitrariness in registration criteria allow subjective judgment by investigating officers. Second, the pre-registration appropriateness review procedures are inadequate. Third, the reinvestigation rate is extremely low. Fourth, victim rights protection is insufficient.　 Through comparative legal review, this thesis analyzes unsolved case management systems in the United States, United Kingdom, Germany, France, and the European Union. Based on these analyses, this thesis proposes improvements to the Korean system. Key improvement measures include: clarifying and objectifying registration criteria, implementing multi-stage review procedures, strengthening the effectiveness of objection procedures, enhancing victim rights protection, expanding scientific investigative infrastructure, promoting public engagement, and expanding dedicated cold case investigation teams. These improvements are expected to enable the Registered Unsolved Case Management System to operate more fairly and efficiently, thereby contributing to the protection of victims' fundamental rights and the realization of criminal justice.
